Abstract
The X-ray absorption fine structure of crystalline selenium under pres sure from 0 to 10 GPa was studied. The pressure dependence of the firs t, second and third neighbor distances was determined by a curve fit a nalysis. The mean square displacement of the first peak increased with increasing pressure while that of the second peak decreased. These ch anges are attributed to the weakening of the covalent bond and the str engthening of the interchain interaction.
